The ‘rice bowl’ of Vietnam, the delta is carpeted in a dizzying variety of greens. It's a water world that moves to the rhythms of the mighty Mekong, where boats, houses and markets float upon the innumerable rivers, canals and streams that criss-cross the landscape like arteries.

The bustling commerce of its towns contrasts sharply with the languid, almost soporific pace of life in the countryside. Here buffalo wallow in rice paddies, coconut- and fruit-laden boats float slowly along the mud-brown waters, and two-wheeled exploration of the narrow lanes is amply rewarded with a true taste of rural hospitality (and delicious river fish).

Elsewhere, mangrove forests teem with a wealth of birdlife and bristle with the remains of Viet Cong bunkers, ornate Khmer pagodas and Buddhist temples reach for the sky, while off-coast islands offer white-sand beaches and tropical hideaways to some, and pirate havens to others.
